This component is only available in the PC version, it is used for creating Imperator Weapons. It is generally only dropped by one-time rare monsters, Bai Ze being one notable exception.

Each weapon requires 20x Blueprint 4 and 1 captured rare monster. Each accessory can be created once per playthrough.

Note that every Imperator item can be purchased at Lucros's Armory in Undelwalt as Trade Goods for less money than the crafting cost. This can only be accomplished if the player has enough Commerce Points in Gem, Equipment and Imperator, selling a minimum of 43 rare monsters.
